Thermal analysis of the Wire and Arc Additive Manufacturing process using the F.E. method
No full textIn this research, a thermal analysis of the wire and arc additive manufacturing process is presented based on the F.E. method. An important quality of the F.E. model that is presented in this research is to describe the temperature field that is experienced by the deposited material in the wire and arc additive manufacturing process. In contrast to the traditional method of monitoring the substrate temperature, the F.E. model allows to describe the temperature field that is experienced by the deposited material constituting both the multilayer weld deposit and the component. Accordingly, the F.E. model is capable to describe the effect of the locally attained temperature field on the microstructure of the deposited material constituting the multilayer weld deposit in terms of the thermal characteristics including the temperature distribution, the locally attained temperature values, the cooling rates and the temperature gradients throughout the component. Two cooling methods are proposed to control the heat dissipation from the component to the environment based on the application of an interlayer waiting time and immersing the component into a cooling medium. The results show a significant effect of the cooling methods on the temperature field that is experienced by the material constituting both the multilayer weld deposit and the component. Indicating that the cooling methods that are proposed in this research are effective to control the microstructure and the temperature field that is experienced by the component in the wire and arc additive manufacturing process. The resulting microstructure is characterised in terms of the microstructural morphology and the microstructural constituents, using optical microscopy based on the average grain size and the distribution of alloying elements throughout the material constituting the multilayer weld deposit. In addition, the average grain size and the distribution of the alloying elements throughout the material are evaluated in terms of the hardness values.Materials Science and Engineerin
PRESENCE AS CYBER-IMMERSION AND INFANTILE LIFEWORLD TRANSITION FACTOR F.E. VASILYUK'S TYPOLOGY
No full textАвтор статьи анализирует психологические аспекты "виртуализации" человека и его бытия в контексте типологии жизненных миров Ф.Е. Василюка. Выдвигается гипотеза о сущностной близости пребывания человека в виртуальном пространстве и нахождения в инфантильном жизненном мире. Автор полагает, что ключевую роль в процессах киберпогружения и перехода в инфантильный жизненный мир может играть нахождение в "состоянии присутствия" как субъективного переживания пребывания в иллюзорном мире, альтернативном реальности.The author analyses psychological aspects of "virtualization" in terms of F.E. Vasilyuk's lifeworlds' typology. The author states that being in the cyberspace is similar to existence in the infantile lifeworld and that the "presence" phenomenon may serve as the key mechanism to cyber-immersion and "slipping" into the infantile lifeworld.111-11

Introduced marine biota in Western Australian waters
No full textAn annotated compendium is presented of 102 species of marine algae and animals that have been reported as introduced into Western Australian marine and estuarine waters, four of which arc on the Australian national list of targeted marine pest species. For each species the authority, distribution (both in Western Australia and elsewhere), voucher specimen(s) and remarks are given. Sixty species are considered to have been introduced through human activity, including three on the list of Australian declared marine pests. The most invasive groups are: bryozoans (15 species), crustaceans (13 species) and molluscs (9 species). Seven of these introduced species, including four natural introductions, have not been found recently and are not presently considered to be living in Western Australia. Twenty six species are regarded as cryptogenic or native. The records of nine species, including two declared marine pests, are questionable or rejected.
The distribution of the 60 introduced species shows that most (37) are temperate species that occur from Geraldton south; only 6 are tropical species that occur from Shark Bay north; 17 introduced species occur in both the southern and northern halves of Western Australia, Because most of the introduced species are temperate species, southern marine areas have more introduced marine species than northern areas. The greatest concentration is in the southwest corner: 46 in Fremantle, Cockburn Sound and the lower Swan River; 25 in Albany and 24 in Bunbury.
We conclude with a strong recommedation that continuing baseline taxonomic research and surveys of the Western Australian marine waters be regarded as an essential component of protecting and managing the State's valuable marine environment
Fairytale Therapy Today: Determining its Boundaries and Content
No full textAbstractPositions existing in psychology in relation to modern fairytale therapy are analyzed while stating the insufficient development of the theoretical basis thereof. Based on F.E. Vasilyuk's ideas on the need to develop a psychotechnical approach, the author believes that fairytale therapy has the features of a psychotechnical system. The article outlines all kinds of approaches to the understanding of the object, methods and essence of fairytale therapy as a special scientific and practical area
Independent magnetotransport in parallel InGaAs double quantum wells with strongly different properties
No full textS.242-246A double quantum well system consisting of two asymmetric In 0.53 Ga 0.47 As quantum wells, of 9 nm and 7 nm width. Respectively, separated by a 4.5 nm In 0.52 Al 0.48 As barrier, has been studied using magnetotransport measurements over a wide range of different total electron densities as well as different ratios of the electron densities in the two quantum wells ns1:ns2. The Hall measurements reveal planteaus for even and odd integer filling factors v. depending on the electron density. SdH and Hall measurements for an electron density ratio ns1:ns2 = 1:2 show integer filling factors V = 3i (i integer). This can be understood by treating transport in both quantum wells as independent. Therefore filling factors v = v1 + v2, with v1 and v2 filling factors of the two quantum wells respectively, are observed. From SdH measurements other basic quantities, such as electron densities, transport and quantum lifetimes and g-factor, were obtained for both quantum wells separately. This leads to the conclusion that the upper quantum well is always less than half as populated as the lower one. it also exhibits a longer quantum lifetime and therfore shows a very pronounced g-factor enhancement, more than four times as large as for the lower quantum well. The pronounced appearance of odd filling factors is therefore understood by means of this very strong g-factor enhancement for the less populated upper quantum well for magnetic fields larger than 4 T.15Nr.

The art of scholarly reviewing: Principles and practices
No full textThe quality and reputation of an academic journal can depend on several factors, but high-quality peer reviews are always a core requirement. Unfortunately, reviews are not always up to the standard that they should be. Poor reviews can result in a number of problems including sub-standard articles being accepted and good manuscripts being rejected. Good reviews are comparable to good papers; they require attention and dedication to write well. Although journals are different, it is important that reviewers approach their task with goodwill, i.e. that they approach a manuscript with an open mind, read it with care and attention and make comments that are constructive and show self-reflection. Reviewers need to know the evaluation standards and the limits of their own expertise and, if in doubt, not to be afraid to say so.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication Technolog
A low number of invasive marine species in the tropics: a case study from Pilbara (Western Australia)
No full textInvasive marine species (IMS) are thought to be one of the most serious anthropogenic threats to global marine biodiversity. There are numerous reports of IMS being introduced into new areas throughout the world, but relatively few are in tropical locations. It has been suggested that this is an artefact of our lack of knowledge species present in the megadiverse tropics and a lack of IMS surveys. The Pilbara in northern Western Australia (WA) is used as a case study to examine these questions. The area is at high risk of IMS because of extensive international shipping. A detailed literature search of marine biodiversity studies developed a database of 5,532 species recorded in the Pilbara. There have been numerous surveys for species on the Australian national and WA IMS lists but only one, the ascidian Didemnum perlucidum Monniot, 1983, has been found
